To add on to that "there are less sword fighters than brawlers" thing:
I like to calculate percentages of things. they make things easier to understand. Do you know what percentage of characters use swords? 32.75% of characters. But here's the catch: That includes every single blade in the game. I included things like Bowser Jr.'s dash attack, and even Zelda's knight. The percentage of characters in the game who use a sword as their primary weapon is 20.6%. Man, 12/58 sword characters is a lot.

Also Corrin uses dragon transformations for exactly 70% of his moveset. He's not even a sword fighter; he just carries one.
